400ex tick worse after valve adjustment.
So I recently adjusted the valves on my 2008 400ex because I started to hear a tick and it got louder and louder, (wasn't horrible but I could tell it was getting slowly louder) so I decided to do a valve adjustment, I know I did it correctly as one of my friends and I have done this many times before on quads, but this was a weird case, after we adjusted them to stock specs, we put on the valve caps and tried to start it to make sure we did nothing wrong before assembling it, when we turned it on it started up with the most disgusting sounding clanking and ticking noise ever, I have no clue where to start to check for issues but its weird that this started after I adjusted the valves, though when I adjusted the valves the valves where 3 turns to tight on the flat head screw which is way to tight, so I am wondering if my cams and rocker arms have worn themselves down so much there's play in them now, if anyone has any idea that would be great and a big help.
